Comment Forth (Score 1) 429

Did you know? (according to wikipedia) "...uses of Forth include the Open Firmware boot ROMs used by Apple, IBM, Sun, and OLPC XO-1; and the FICL-based first stage boot controller of the FreeBSD operating system."

I only vaguely remembered reading that somewhere, but I did know that are/were many Forth controlled Telescopes (which led to a better understanding of the cosmos.)

Personally, I used it back in the day to make very compact mission critical 24/7 programs.

Comment Re:Home school (Score 2) 529

The problem with a general solution in education is that it does not exist. Period. Since no two people are alike in their learning styles, attempting a cookie-cutter solution is basically what our public school system has been doing and failing miserably at for umpteen years.

Yes, one *COULD* use home schooling to mold one's children into carbon copies. One *COULD* use the system to avoid "evilution". But one could also use it to stimulate critical thinking, independent and insatiable learning, and deep understanding of this world.

It is amazing that people usually blame the implementation of ideas, but not the ideas themselves, when things go wrong.

Comment Similar to deniable encryption... (Score 1) 106

The goal stated in the article is similar to that of deniable encryption. Whereas "honey encryption" works through a piece of dedicated software, deniable encryption works by constructing a block of ciphertext in such a way that different plausible plaintexts can be recovered depending on which symmetric key is used for decryption. Of course, only the user knows how many different plaintexts are actually buried in the ciphertext, and under duress (rubber hose, point of a gun, etc.) he can relinquish the non-incriminating plaintext and claim innocence.

Submission + - 6 Weird Habits Of Successful People (

They are quitters. You know the saying “Winners never quit and quitters never win.” Not so much. In fact, that’s wrong. Winners quit a lot. They have a keen eye for what is not working and not supporting the finish line (check rule one again for that). Once they identify the thing sucking energy, money and resources from their business, they cut it out fast.

I liked it. I think you might, too."

Comment Re:i hate dirty fingerprints on my screen (Score 1) 526

Real Job, Real Experience, Real Place, with fire and smoke and occasional explosions. You would recognize the initials. We received a touch screen device. Very cool. Very expensive (money was not a problem). I was trying to get my point across to the operator, so I pointed (OK. I POKED) at the object on the screen.

It was not a good day. No one was killed. No equipment was damaged. I don't even think we really lost any data or too much schedule. But the implications of what could have happened were obvious. It was an often repeated story, that resulted in an un-official but institutional ban on all touch screens in the facility for the next 20 years.

Today I love multitouch, especially on tablets, phones and on my laptops and desktops when used with a horizontal trackpad or mouse with a touch surface.

Not sure I'll ever feel good about touching a vertical screen though.

Comment Re:Is it permitted to include anti-copying code? (Score 1) 12

"How does it make sense to claim software is free-as-in-freedom if it's designed with DRM or other anti-piracy measures? "
I think the pro "Tivoization" argument was that just because I'm obligated to share what I have done for free or nominal cost - possibly for educational value, I don't have to make "easy" for you to simply copy and use my work, and not put in your own blood sweat and tears. GPL 3 was intended to clear this up - I do have to make it easy and cheap for you to use my derivative - and legal - if I distribute my work. BTW Linus T. didn't agree with this change according to some articles I read. He was OK with Tivoization so long as he got to see the source code of the derivative.

"Can you even technically pirate GPLed software to begin with?"
Maybe. You aren't required by the GPL (either version) to distribute your derivative work. Only that you don't limit the rights of those you do distribute it to, - if they are outside your organization. Within your organization, for instance, Google or Amazon, you can have custom versions of GPL'd software that are trade secrets and could presumably use DRM to stop the distribution outside of your intended internal use, or to track who let it loose.

So getting a copy of a private version of a GPL'd derivative, intended for private use - could be considered piracy.

Just a thought - not dogmatic about the thought at all.

According to the wikipedia this was a provision added to GPL 3 to overcome a weakness of GPL 2. So if the code was derived from GPL 2 maybe not.

In explaining the changes:
"It also adds a provision that 'strips' DRM of its legal value, so people can break the DRM on GPL software without breaking laws like the DMCA.[27]"

Not agreeing with the developer - just saying he may have some legal ground to stand on. (I don't pretend to be a lawyer or even know when to hire one. )
